Letters Patent No. 74,248, dated February 11, 1858.

vIMPROVEDIENT IN IMPLEMBNT FOB. CUTTING TOBACCO AND OTHER SUBSTANCES.

at Segnale naman it tigen when @aient-'ant making part nf tij: samt TO ALL TO WHOM THESE PRESENTS `SHALL COME:

Be it known that I, DANIEL T. ROBINSON, of Boston, in the county ofSuifolkr and Commonwealth of Massa.'- chusetts, have invented a. new and useful Implement for Cutting Tobacco and other Substances; and do hereby .declare the following to be a full, clear, and exactdes'eription thereof, due reference being had'to the accompanyingdrawings, making part of this spcification, and in which?,

Figurel is a vertical and longitudinalV section, Figure 2 a vertical and transverse section, and Figure 3 a horizontal section of my invention. The principal objects I have sought to accomplish in this invention are simplicity and oheapness of construction, and, `at the saine time, effectiveness in operation.

The invention consists in a lever, pivotcd, at its upperfront end, to the top of a etationarystandard, and having a right-angular arm depending' from. it, immediately in rear of its fulerum or pivot; a knife or blade being in turn pivoted, at its front cnd,to the lower extremity of such arm, and having its opposite end slotted and supported by a friction-roller, in manner and to operate as hereinafter explained. l

In the vaccomp'anying drawings, A denotes a block of wood, or other suitable material, having ailixcd to ono end of its upper surface a post or standard, a. Along lever,l shown atb, is pivoted at one end of the upper part ofthe post a in such a manner as to allow of vertical movements therein, the lever being constructed with an arm, c, depending from it, at right angles or thereabouts, immediately in rear of the post a, to the lower extremity of which one end of a. metallic knife or blade, d, (sharp'upon its lower edge,) is pivotcd. The opposite end ofthe knife d is formed with a slot, e, made through an angle of thirty degrees, or thereabouts, into which slot a.friction-rollcr,f, extends and supports this end o f the knife, the roller'f being supported by and revolving on a horizontal pin, g, passing through the upper end of a second post or guide, z', this post being slotted vertically, for reception of the knife, and to guide its vertical movements.

It will of course be evident that on raising the handle a` of the lever b, the knife d will be raised above the ,surface of the block or bed A, a sullicientldistance to allow the introduction under it ofthe material to be cut.

On depressing the handle, the knife descends within a'd'lrection between a vertical und horizontal-one, or at such an angle as to produce a drawing-stroke, as it is tei-mcd, or. one which has been found in practice the most effective for cutting tobacco, for whichpurpose the present inventionis intended, although its principles of con'- struction may be applied for cutting various materials.

I claim as my invention, and desire to secure by'Letters Patent of the United States- The above-.described implement for cuttingtobac'co, consisting of the block or hed A., post a, lever b,'n.nd knife d, the knife being constructed with the slot e, and provided with the rollerf, or its equivalent, for actuating its movements, and supported within 'the guide z', .the whole being constructed andopcrating substantially as herein shown and described.

DANIEL T. ROBINSON.
